The old logic here was turning all breaks that pass through an
escaped proc into LongJumpError, even if they originated in a
different frame/proc that could still validly handle the break.
This commit modifies the logic to ignore the exception altogether
(re-throwing it) if it is not associated with this proc/frame (by
checking jumpTarget).

Fixes #1270

This commit puts JavaSupport back the way it was, so we can git mv
instead and get merging across that move.
